4 Inch Inlet 8 Inch Outlet Polished Stainless Steel Miter Cut Diesel Exhaust Stack Diesel Exhaust Tip(Stack Smokers 4" ID Inlet 36" Long)

I have a 6.5 straight pipe 3-5-7 out the box, awesome sound, easy peasy install, two thumbs up

Exactly what i thought it was and what i wanted makes the truck sound mean and echoey

Materials are top notch

I was not prepared for the actual size of this tip. It sounded sooo good on my 6.6 duramax, it’s crazy the difference in sound a simple cylindrical piece of steel can make. Definitely worth the price.

Awesome sound

Been looking how to contact seller. Stacks were installed maybe 3 weeks ago, one of them is already cracked down the seem roughly 4 inches. It’s the right side of both stacks I bought looks like a crease type seem. Can’t seem to find any customer support number

Is what the descripton says, but the weld quality isnt great, there is a very visable seam down entire side, also making it not perfectly round.

Pipe arrived in a Amazon box opened that box up to find a screw up box opens it up to find a dent on the top of the stack and pits all over under the paint lucky my plan was to axle dump it so needed to be cut down some and won’t be seeing it enough to worry but would not buy if actually using for a stack
